- Subject: PROG476 (DFT buffer error)
- Lines: 15
-
- We run VTAM on MVS/ESA and NCP on a 3720. We have a 3274-61C configured
- for 16 BSC terminals with 4 currently attached. Two are 3179s and 2 are
- PC 3270s configured as non-SNA DFTs. The terminals are used for CICS
- transactions. A particularly "big" CICS transaction causes a PROG476 on
- the 2 PC 3270s but works on the 3179s. (Other smaller CICS transactions
- work fine on both types of terminals.) The explanation for PROG476 in
- the 3274 CU Desc and Prog's Guide says the DFT's buffer overflowed.
-
- I DON'T KNOW WHAT TO DO ABOUT THIS BUFFER PROBLEM.
-
- I looked at PC 3270 config procedure in 3270 CP User's Guide and Ref,
- tried different log modes, looked in NCP Resource Def Ref but couldn't
- identify a solution. I found some VTAM buffer keywords and the CICS
- system programmer mentioned something about in-bound and out-bound
- buffer sizes. Can anyone tell me where I should be looking? Thanks.
